<h1>Going further...</h1>

The <a href=sample.gui>sample script</a> introduced in the 
<a href=gagui_sample.html>previous section</a> 
has covered most of the
GAGUI functions and callbacks. However, there are just a few things
that were left out that you may find handy sometimes. 
Please consult the following sample scripts:

<ul>

<li> <a href=sample.gui>sample.gui</a> - this is the script that
     we covered in the <a href=gagui_sample.html>previous
     section</a>

<p>

<li> <a href=sample2.gui>sample2.gui</a> - a slight variation 
     of <b>sample.gui</b> with a different layout (single row).

<p>
<li> <a href=melrose.gui>melrose.gui</a> - similar to
     <b>sample.gui</b> but customized for DAO's visualization server
     (melrose.gsfc.nasa.gov). Here is an example of how to associate
     <font color=#ff0000>Help</font> menu items with documents on the Web.
     It also contains buttons to open files from the GEOS-1 Reanalysis 
     residing on a local disk. DAO users on melrose can run this script
     with the following GrADS command:
<blockquote><b>
     ga-> gui /ford1/local/lib/grads/gui/melrose.gui
</b></blockquote>
     or they can set
<blockquote><b>
     setenv GAGUI /ford1/local/lib/grads/gui/melrose.gui
</b></blockquote>
     for starting it automatically.

<p>
<li> <a href=ncep.gui>ncep.gui</a> - similar to
     <b>sample.gui</b> but has one additional row which allows
     the user to open files from the NCEP/NCAR Re-analysis CDROM,
     the disc that came with the <i>Bulletin of the American Meteorological 
     Society</i> (Kalnay et al. 1996).    
     This script illustrates the <b>chdir()</b> function which allows 
     the changing current directory to the CDROM mounting point. It also
     includes a <i><font color=#ff0000>Help</font></i> button
     which displays ASCII documentation files in the CDROM.<br>
     <b>Note:</b> This is script will not work with the
     <i>Annual Re-analysis CDROMs</i> being distributed by NCEP.<br>
     <b>Exercise: </b> adapt this script for the <i>Annual Cdroms</i>
     and contribute your script <b>:-)</b>

<p>
<li> <a href=window.gui>window.gui</a> - this script illustrates 
     how to create
     a secondary GUI window which can be dismissed when no longer
     needed. For trying it, start one of the main GUI scripts such as
     <a href=sample.gui>sample.gui</a>, and from the 
     <i><font color=#ff0000>File</font></i> menu, click on
     <i><font color=#ff0000>GUI</font></i>, entering the name of
     this script (which, of course, should be copied to your
     local disk). A secondary window will pop up with buttons
     for opening files in the NCEP/NCAR Re-analysis CDROM,
     similar to the middle row in 
     <a href=ncep.gui>ncep.gui</a>.

</ul>

Of course, for getting all the glory details you will need to read the
<a href=gagui_ref.html>Reference section</a>.
